摘要
为明确城市雨水利用系统的综合效益,以促进其在城市的推广应用,需要客观、准确地评价城市雨水利用系统。提出了城市雨水利用系统的评价指标体系,利用层次分析法确定权重,并采用模糊综合评价法结合灰色系统理论,建立了灰色模糊综合评价模型,并结合雨水利用实例进行了研究。结果表明运用灰色模糊综合评价法来分析、解决雨水利用系统方案具有准确性和有效性,有一定的应用价值。
In order to make clear the comprehensive benefits of urban rainwater utilization system to promote its application in the cit y, the urban rainwater ulilization system is needed to be evaluated objectively and accurately. An evaluation index system for urban rainwater ulilization system is presented , and an evaluation model is established by adopting Analysis Hierarchy Process to ascertain right weight and combining fuzzy comprehensive evaluation method with the Grey System Theory. Example study is conducted and the result validates the accuracy , validity and certain practical value of using grey fuzzy comprehensive evaluation method to analyze the rainwater utilization system solution.
